In the accompanying drawin s I c nveyer 1n the usual manner.

have illustrated one complete example 0 the At the lowerend of the hanger-frame are physical embodiment ofmy invention wherearranged two parallel bars ;8, 8','forming rigid in the parts are combined and arranged acparts of the frame and extending ina plane cording to the best mode I have thus far deparallel with the plane of'theoverhead rail,

.. shaped'b'ail 14, the bail 1e beingiprovided 1 I thebucket; Each diskis; fashioned with a with abearing plate 15 bolted to the underside of the angular bail, and it will be apparent in Figure 4 that the apex of the angular bail and its bearing plate 15 form a pivotal bearing, between the two bars 8, 8 on the pin 9. The bail is thus permitted to swing on the transversely arranged pivot pin, after the latter has been passed through the, bearing and is supported in the bars, but the two bars prevent lateral swingingof the bail. While the bucket 13 is held rigid with its bail, as

will be described, it will be apparent that the bucket cannot sway or swing laterally, because-of the arrangement of the bail and the two bars, and the bucket is therefore held against relative lateral zmovement 'by the hangerefralne. r I

I At the lower endsof the bail are provided apair of open brackets 16, bolted at one side of the'bail', and eachprovided with an opening -17 T'anda smaller bearing slot 18 at the lowermost end of the bracket;

Atthe exterior of and on opposite ends of the bucketare mounted circular disks 19 and '20'whichare'secured to the bucket by bolts 21passing through holes '22 in the disks and the bolts'of cou-rsepass through the walls of trunnion23 and each trunnion has a head 24:, the latterof ais'iz-e tobe passed through the large opening 1?- of the -bracket,-but the head i is larger than the bearing slot 18 which re 35. ure2, the bucket is thus pivoted at points ceives the trunnion, and the head prevents dislocatlon or displacement of the trunnion fromuits bearing slot. As best seen in Figoffset from the bail, and the bucket isiadapted to swing clockwise in Figure 2, to inverted: position for dumpingits load, after the bucket has been released from its rigidconnection withthe bail. I

At least one of the-circular disks, as 19, is

provided with a peripheral notch or socket 25 and the periphery of the diskis adapted to turn adjacent the inner side of the .bailebracln' et. A lever arm orlatch-arm 26 is located in 1 thesame plane with the disk and adjacent its cured on one wall of the notch. or socket to guide the head, and to hold it against lateral movement. A trip lever is secured in a groove 31 1n the face of the latch arm, and

is secured rigidly to the arm by bolts or screws I The lever 30 projects in approximately socket 25.

7 A roller or other contact device, as 33 is v -inounted'on the end of the bucket, as indi-' tion retains the bucket against turning movement on its trunnions.

When the bucket approaches its dumping station the free end of'the lever rides upfla stationary incline or cam face'which causes th lever and its rigid latch arm 26-to swing upwardly on the pivot 27 thereby withdrawlng the latch head 28 from its notch cated in Figures 2 and 6, above the lever and in 1ts path of movement, and when the lever is lifted to release the latch the former contacts with the roller 83, thereby tilting the bucket to turn clockwise in FigureQ, and the bucket in turn inverted or turned to dumping position by gravity. ,7 I r j V The weight ofthe lever 30 causes the leverlatch to fall, after the lever leaves the cam i or incline,and thehead 28 of the latch falls against the periphery of the disk 22, and re; mains in frictional. contact with the peripheryof the disk. When the bucket is again righted or turned to loading position by suit able means, the socket 25 turns to proper positlon to permit the head'to fall into it, and

the bucket is then retainedinrighted p'osition, or,latched,vto receive its next load.

' The bucket may readily be removedfrom its suspending bail by first lifting the bucket to free its trunnions from their bearing slots 18, and then the trunnions'may be worked out through the openings 17, or thebucket and. bail may readily be detached from the hanger frame, by first removing the cotter pin 12 and then pulling out the pivot pin use 9, if repairs or replacements are necessary. 7

Having. thus fully described my invention, what I claim as" new a and desire to Lettersv Patent -is:, 1
